Suitable for high-speed cutting of difficult-to-cut materials such as stainless steel. For difficult-to-cut materials whose thermal conductivity is low and the tip temperature rises easily during cutting, the unique shape of the blade can suppress the effect of cutting heat on the tip.

In D.C., public-health and LGBTQ+-rights advocate Antonio Cornelius Baker died unexpectedly at his home of natural causes on Nov. 9, The Washington Blade reported. Among the numerous organizations to which he provided support and guidance was the Elizabeth Taylor AIDS Foundation. That organization said in a statement that “A. Cornelius Baker stood with our founder, Elizabeth Taylor, at the beginning of the HIV/AIDS movement and throughout her legacy … We find comfort in knowing that his spirit, along with Elizabeth’s, will continue to guide and inspire us and the entire HIV/AIDS movement in our ongoing work.” Baker’s career in public health included being special adviser to the Office of AIDS Research at the National Institutes of Health, and being executive director of D.C.’s Whitman-Walker Health and the National Association of People With AIDS. National Black Justice Collective CEO and Executive Director Dr. David Johns said separately, “We were honored to include A. Cornelius Baker in our inaugural class of James Baldwin Legacy Award honorees in 2021. We will continue to honor his legacy with our actions to eradicate the HIV/AIDS epidemic in America and across the global community.”

Ejecting the chips at a more acute angle is another way in which a higher helix might assist with chip management. In materials in which we purposefully aim to disperse the heat on the chip itself, proper chip evacuation may assist avoid chip packing or re-cutting of chips, which can be a costly process. Higher helix angles are often suggested because they operate well on sticky materials like as aluminum, and they excel in stainless steel and heat resistant alloys. On the other hand, the size of the helix directly correlates to the amount of reinforced strength that each cutting edge has. There is a risk that a high helix may assist pull the end mill out of the collet featuring because of the larger vertical force that it exerts. This is one of the drawbacks of having a high helix (however most end mills pulling out of collet featuring is due to user error or cutting parameters that are too aggressive, or the end mill not being tight enough in the collet).

Because of the increased radial stresses caused by low helix angles, these tools are more susceptible to vibration and bending. These cutters, on the other hand, are capable of tremendous rates of material removal and huge chip loads. Because of this, they are an excellent choice for procedures involving roughing.

The use of a big spiral angle end milling cutter is beneficial to extending the tool’s lifespan while cutting stainless steel materials that are challenging to work with because they have limited thermal conductivity and have a significant impact on the blade tip’s heat.

Voters in three states—California, Colorado and Hawaii—passed ballot measures that would amend language in their state’s Constitution to protect same-sex marriage, USA Today reported. Before same-sex marriage became legalized nationally, efforts to legalize the practice popped up in the 1990s, according to Human Rights Campaign; however, the 2015 U.S. Supreme Court pro-marriage equality ruling struck down same-sex marriage bans in 13 states. Supreme Court Justice Elena Kagan warned in a September interview with the New York Times that she thinks same-sex marriage and contraception are under threat after the 2022 Roe v. Wade decision.

The helix angle also alters the features of the completed surface. For instance, high helix angle end mills may sometimes be utilized when machining with a smooth finish is necessary. However, the cutting resistance will rise and the force of the proper spiral angle cutter will increase when using an end milling cutter with a big spiral angle. As a result, appropriate actions must be taken, including employing a tool handle with strong clamping stiffness. Although the cutter’s stiffness may be guaranteed, narrow spiral angle end mills are sometimes utilized when cutting workpieces with low rigidity, such as thin plates.

Also in the Lone Star State, Gilberto Hinojosa—the chair of the Texas Democrats since 2012—will resign after the party’s bruising election losses and some controversial comments he made, Texas Public Radio noted. The resignation announcement came the day after Hinojosa apologized for telling The Texas Newsroom that immigration and transgender issues hurt Democrats at the polls. LGBTQ+-rights groups and trans-rights advocates criticized Hinojosa’s remarks, saying he was blaming Democrats’ most vulnerable supporters for his and the party’s shortcomings.

An end mill’s helix angle is determined by the angle that is produced between the centerline of the end mill and a straight-line tangent along the cutting edge. This angle is measured in degrees. End mills designed specifically for cutting aluminum often have helix angles that are steeper than those seen on regular end mills. In most cases, the specialized helix angles for aluminum range from 45 degrees to 55 degrees. You may also get variable helix end mills, which are a terrific option for lowering chatter and harmonics while simultaneously increasing the amount of material removed from the workpiece. For more conventional roughing and slotting operations, a helix angle in the range of 45° to 55° is a reasonable option.

Axios ran a piece on The Heritage Foundation’s Project 2025, which President-elect Donald Trump’s allies have touted as the incoming administration’s agenda—and it outlines vast plans for rolling back rights and protections for LGBTQ+ people. For example, Project 2025 attempts to virtually erase LGBTQ+ people from federal protections altogether, suggesting the deletions of “sexual orientation and gender identity (SOGI); diversity, equity and inclusion (DEI); gender; gender equality; gender equity; and related terms. Among other things, the project also calls for transgender people to be banned from serving in the military; an end to federal funding of DEI programs; and calls for cutting federal funding for gender-affirming care and cracking down on “abortion training” at medical schools.

In a ball nose end mill, the helix angle ranges from 30° to 35°, and it has a distinctive groove structure. These two features allow for high-speed processing while also providing great wear resistance. The surface roughness that is achieved after processing is satisfactory when using a chip breaker with fine teeth. Adopt a coating that is both highly lubricious and resistant to high temperatures.

What you intend to do will determine which tool is most useful for you to employ. The higher 45° helix is well suited for finishing applications, in which the tool is operating noticeably quicker but removing less material, whereas the slower 35° helix is well suited for roughing applications due to its increased strength and capabilities to carry a bigger chip load. This is because the higher 45° helix is ideal for finishing applications, in which the tool is operating considerably quicker but removing less material. In circumstances in which tool versatility is of the utmost importance, the medium 40° helix is a reliable choice since it can be used for both roughing and finishing, and it strikes a healthy balance between the benefits of slow and high helix angle.

Standard end mills are available with helix angles ranging from 15° to 60°. End mills for common use typically have a 30° angle. Any increase in helix angle reduces cutting forces and the amount of heat produced during milling by increasing the effective shearing action. Also enhanced is chip ejection. End mills with a lower helix angle are used on harder-to-machine materials where maximal edge strength and stiffness are crucial.

The tool has excellent stiffness because to its adoption of a multi-edge design, and this allows it to reduce the amount of tool allowing in that occurs during side cutting. Sharp corners guard the cutting edge, which reduces the likelihood of the innovative chipping.

The Texas A&M University System Board of Regents directed the president of its flagship school to end 52 low-enrollment programs, including a nascent LGBTQ+ studies minor that conservative state legislators have cast as “liberal indoctrination,” according to Inside Higher Ed. Faculty members have opposed the move, voting earlier this month to reject the proposed program cuts. University president Mark Welsh objected as well, asking that the “review process be halted and restarted to obtain input from the Faculty Senate,” according to board documents.

The effectiveness of the machining application is affected by a diverse selection of factors in various ways. It is common practice to ignore the helix angle. The helix angle is responsible for controlling the angle at which the cutting edge of the tool enters the work piece as the tool rotates. The helix angle must be increased for the entry of the cutting flute to happen in a more gradual manner. This results in a transition that is smoother as the cutting flute works its way toward achieving the desired axial depth of cut. Straight and spiral are the two primary styles of edge that may be found on carbide end mills. There are many different sorts of helix angles, such as 30 degrees, 45 degrees, and 50 degrees. In milling operations, the edge end mill has been used widely because, in comparison to the straight edge, it provides the advantages of light cutting, smooth cutting, high efficiency, and a wide range of applications. This has led to its widespread adoption. Now that we have that out of the way, let’s talk about how to choose the appropriate helix angle for the end mill.

A Texas politician became the first openly LGBTQ+ person elected to U.S. Congress from a Southern state, The Houston Chronicle noted. Julie Johnson took over Colin Allred’s North Texas seat for House District 32 after the Nov. 5 election, beating Republican Darrell Day 60%-37% to represent a district that serves Collin, Denton and Dallas counties. Queer representation in politics isn’t a new focus for Johnson. The representative was a founding member of the LGBT Caucus in the Texas House of Representatives, where she has served since 2019 for District 115. Johnson also married her wife, Susan Moster, in 2019—making Moster the first same-sex spouse of a Texas legislator.

Finally yet importantly, the angle of the helix is one of the most important characteristics of the helix edge end mill. The degree to which the helix angle is altered has a significant bearing on the cutting efficiency of the tool. The modification of the helix angle in the course of tool production has been feasible thanks to the development of CNC machining technology. When manufacturing and selecting spiral-edge end mills, it is important to combine the performance of the machine tool and tooling fixtures, according to the performance of the processed material and the processing accuracy. Comprehensive consideration of factors such as machining efficiency, tool material and tool life, and optimizing the size of the helix angle will undoubtedly improve the cutting performance of spiral-edge end mills.

Republicans in the Ohio Senate passed a bill to make changes to the state’s College Credit Plus program—and it has an added requirement that transgender students use bathrooms that match the gender on their birth certificates, Statehouse News Bureau reported. Senate Bill 104 is headed to Gov. Mike DeWine after this vote, which happened in the first legislative session following the election; he’s likely to sign it. Eleven states—Alabama, Arkansas, Florida, Idaho, Iowa, Kansas, Kentucky, North Dakota, Oklahoma, Tennessee and Utah—have some form of a bathroom ban. All of those states, along with Ohio, went red in the recent presidential election.

When using straight flutes, the load increases nearly immediately, which makes the end mills susceptible to self-excited chatter. Helix angles provide chip stress to the whole length of the flute in a progressive siding motion akin to a ploughs with a blade that is slanted off to one side. As a result, there is far less risk of noise and the cutting forces are much steadier. Higher helix end mills also often result in significantly superior work piece finishing. Helix angles of 50° and greater greatly lessen side stress on the mill, enabling peripheral milling of thin wall sections with much less deflection.

Higher helix angles are more flexible and less likely to vibrate and bend during the cutting process, which helps to lessen the amount of radial force that is exerted. They are able to generate an excellent surface polish, making them ideal for operations related to finishing.

In Iowa, first-year Grinnell College student Kenya Taylor is seeking felony charges against a Durant, Iowa man accused of assaulting him at an on-campus party and calling him an anti-gay slur on Nov. 2, per The Scarlet & Black. Taylor, a gay Black man, said he was kicked in the back, chased into a corner and punched in the mouth by alleged perpetrator, Noah Grage, 19, who does not attend the school. (Grace said he was invited to campus by a college student he met online.) Taylor said Grage called him a “fairy f****t” hours before the incident. Grage said it was “fully reasonable” that Taylor is seeking criminal charges against him. “I mean, I hit the guy, I guess,” Grage told The S&B. “I can’t say that I would do the same, but it makes sense.”

Lower helix angles provide improved edge strength, which is beneficial in materials like cast irons and tougher steels. Tools having a helix angle of less than 40 degrees are often better suitable for roughing tasks because to their increased strength. However, the finishing quality is diminished when using these sorts of tools; however, this drawback may be circumvented by performing a finishing cut with a higher RPM and a slower feed, during which the tool takes away just a little quantity of the material being cut. Therefore, applications that need heavy cutting and where finish is not as much of a concern are better suited for tools with a low helix.

Alabama Shipyard LLC has been chosen to perform maintenance on the U.S. Navy’s new replenishment oiler, the USNS Harvey Milk, AL.com reported. The company was awarded a $24.5-million firm-fixed-price contract to perform the post-shakedown availability (PSA) on the oiler, which will provide fuel to the Navy’s surface combatant ships at sea. The ship—the Navy’s first named for an openly gay person—honors Navy veteran and LGBTQ+-rights activist Harvey Milk, one of the first openly gay candidates elected to public office as a member of the San Francisco Board of Supervisors in 1978. (Ex-co-supervisor Dan White assassinated Milk and Mayor George Moscone in 1978.) At the ship’s christening in 2021, Navy Secretary Carlos Del Torro noted that Milk resigned his commission and was discharged from the military branch for being gay.

In conclusion, a machinist has many considerations to make while selecting the appropriate tools for each job. A machinist is required to take into consideration the helix angle of each tool in addition to the material, the criteria for the finish, and the permissible run times. Using a helix angle that is too high when it is not required will shorten the life of the tool, and using a helix angle that is too low when it is not required can cause chattering and a poor finish. The whole information on the helix angel option for end mill can be found up above; we hope that it will be helpful to you. Feel free to get in touch with Huana if you need any more information!

In California, gay San Jose City Council member Omar Torres resigned from office shortly after his Nov. 5 arrest, the Bay Area Reporter noted. Torres faces three felony charges related to allegedly sexually abusing an underage relative decades ago. The charges are apparently not connected to a criminal investigation launched by police last month after Torres admitted in a text message that he had sex with a 17-year-old. Torres, 43, had represented downtown San Jose and the Qmunity District, the city’s queer neighborhood; his election two years ago had ended a 16-year drought of LGBTQ+ representation on the city council.

The helix angle of an end mill is defined as the angle that is generated between the cutting edge and the centerline of the tool. Because of the helix that this cutter has, the chip load that is carried by the helical flutes of the end mill continues to grow. It suggests that the pressures begin to slowly increase at the point where the bottom point of the cutting edge first enters the material being cut, and continue to do so beyond that point. The cutting force of an end mill is composed of axial and radial components, respectively. The vibrations are caused by the radial component, which has a tendency to bend the end mill and presses it against the holder, while the axial component presses the end mill against the holder. Depending on the angle of the helix, there may be variations in the distribution of forces along the edges.

Republican Eric Hovde has refused to concede defeat to LGBTQ+ incumbent Tammy Baldwin in the Wisconsin Senate race, casting doubt on the results despite a lack of evidence of any wrongdoing in last week’s election, NBC News noted. In a video on X, Hovde said he was considering whether to seek a recount in the battleground state contest. Baldwin had led by fewer than 30,000 votes, 49.4% to 48.5%, with 99% of the vote counted.

The standard angle of the hss drill bit usually depends on the hss drill bit material and the material being processed.

There is value in using a variety of helix angles since each angle will result in a distinctive set of outcomes. A higher helix angle may result in less tool pressure, which in turn can lead to better finishes and less heat accumulation. When compared to helix angles of a lesser degree, a 45-degree helix has the potential to boost the vertical force of a tool, which eventually results in less strain being placed on the cutter. The progressive entrance of the cutting edge enhances the tool’s efficacy. This is true whether the advanced cutting tool programs are being used in a machining center or the tool is being manually machined. This is because the higher helix angles can be fed at a greater rate.

Edison Research—which conducts national election exit polling for CNN, ABC, CBS and NBC—found that 86% of respondents who identified as “gay, lesbian, bisexual or transgender” voted for Kamala Harris, while 13% voted for Donald Trump, according to LGBTQ Nation. It should be noted that the poll—which had more than 22,000 respondents—was only conducted in 10 “key” states and two randomly selected days before the election to catch early in-person voters. The same poll in 2020 found that only 64% of LGBT people voted for Joe Biden, while 27% voted for Trump.

D.C. police confirmed that a gay man who worked as a hairstylist and a DJ and who was found unconscious on Oct. 27 near the LGBTQ+ bar Uproar has died, according to The Washington Blade. Friends who knew the victim, Bryan Smith, stated in a GoFundMe message seeking support for his medical expenses that he was hospitalized for a severe head injury. His family members told Fox 5 News that he was in a coma. Authorities also released a video showing two suspects and a vehicle they believe the suspects used in committing the robbery of Smith.

More than 1,000 queer candidates ran for elected office this year—and 668 made it to the general election, per NBC News. The LGBTQ+ Victory fund found that more than 90% of the total number of candidates were Democrats, and they ran in every state except Nebraska, seeing wins in at least 40 states, along with Puerto Rico and D.C. This year’s LGBTQ+ candidate pool was also more diverse than ever, with 37.6% of candidates being people of color and 15.2% not cisgender.

In a related matter, a top aide to Democratic U.S. Rep. Seth Moulton (Massachusetts) resigned after comments Moulton made about transgender athletes were criticized by state Democrats and LGBTQ groups, Politico noted, citing The Boston Globe. Matt Chilliak—Moulton’s campaign manager and director of his “Serve America” political committee—departed Moulton’s office on Nov. 7. In a New York Times story about Democratic finger-pointing, Moulton was quoted as saying his party leaned too heavily into identity politics, allowing Trump and Republicans to score a decisive victory, and he added, “I have two little girls. I don’t want them getting run over on a playing field by a male or formerly male athlete but, as a Democrat, I’m supposed to be afraid to say that.” A second House Democrat, Rep. Tom Suozzi (D-N.Y.), told the Times that trans girls, who he called “biological boys,” should not be able to participate in female sports.

SheNYC—a nonprofit organization that fosters women and trans creators through its off-Broadway season and summer festivals—has become involved in a controversy with the Archdiocese of New York, its landlord, per New Ways Ministry. The archdiocese has now required that the theater company cease productions that church officials claim contradict Catholic teaching, particularly concerning abortion and gender identity. The theater is part of the Cornelia Connelly Center, a full-scholarship Catholic girls school “admitting students who would most benefit from additional academic and social-emotional support” in grades four through eight—and the school has currently ceased all activity at its theater. As a result, the theater company is facing its 2025 season—also its 10th anniversary—without a home.

On Nov. 23, the PTA (Patience, Tolerance, Acceptance) Dinner Club—a Wisconsin gay men’s organization always consisting of 12 members—will hold its last soiree, according to On Milwaukee. Started in 1949, the name came about, in part, because most people would just assume that “PTA” stood for Parent-Teacher Association. Over the past 75 years and 898 meetings, the club (which has battled lack of recognition/interest in its latter years) has only had 71 total members. The final dinner will take place at the Milwaukee Public Museum, before the group disbands forever and donates its archives to the Wisconsin LGBTQ History Project.

Curtis Bashaw, the openly gay Republican candidate for New Jersey’s U.S. Senate seat, sparked backlash within the LGBTQ+ community after signing the Moms for Liberty Parent Pledge—aligning himself with a group designated an “extremist” organization by the Southern Poverty Law Center, per The Advocate. Garden State Equality, New Jersey’s largest LGBTQ+ advocacy group, criticized Bashaw for aligning with an organization that has actively promoted policies undermining LGBTQ+ visibility in schools. Bashaw’s stance also sharply contrasted with that of his opponent, Democratic U.S. Rep. Andy Kim, who eventually won the contest, according to Politico.

For common milling applications like as slotting, profiling, and plunge cutting, square end mills are often utilized as the cutting tool. The cutting diameters of keyway end mills are intentionally undersized throughout the manufacturing process. This allows the mills to create a keyway slot that precisely matches the dimensions of the woodruff key or keystock. In most cases, the specialized helix angles for square end mills range from 35°-45° degrees.

In a victory for abortion-rights advocates, New Yorkers voted to enshrine extensive anti-discrimination protections into their state constitution—permanently insulating the rights of pregnant people, abortion seekers, and the queer community, among others, Mother Jones noted. Opponents had mounted an openly transphobic campaign to block it, spreading misleading claims about Prop 1’s effects on a range of issues, including trans youth health care, women’s sports and noncitizen voting; in addition, conservative billionaire Richard Uihlein dropped $6.5 million in an effort to defeat the measure. Going into Election Day, supporters of abortion rights had won every single ballot initiative to go before voters since the U.S. Supreme Court overturned Roe v. Wade in June 2022.
